Ordinurv cement constructions, and morc particularly cement floors, soon undergo in use a superficial disinteqration, yielding a line dust, which is highly injurious to delicntc machinery, and particularly to electrical installations. I have discovered that such surface disintegration can be prevented by treating the cement with certain organic acids or acid bodies, mypreferred procodurc.

being as follows: I first apply to-the cement floor, wall, or other, constructiona'fillcr are pared from a highly-acid resin, such as hisnila or on al gum. For the prepnration of the filler t to resin is heated, togcthcr with a suitable vegetable (Irving-oil or mixture of oils-as, for inst-mic linseed and chinawmnl oils-under conditions which will substant-ially avoid the loss of. volatile resin acids. This heating is preferably effected in vacuo, although the method technicallv known as underheating may be used. he heating is continued-until solution is effected, after hnl'd nnd dlu'ulJlc-contlug; in which no surl'ucc disinlcgruliou will incur. crcn :d'lcr u long period of usc.
